568dc27a19 Make base16_decodes return number of decoded bytes
base16_decodes() now returns the number of decoded bytes. It's interface
changes from returning a "int" to a "ssize_t". Every callsite now checks the
returned value.

Fixes #14013

53a3b39da1 Add -Wmissing-variable-declarations, with attendant fixes
This is a big-ish patch, but it's very straightforward.  Under this
clang warning, we're not actually allowed to have a global variable
without a previous extern declaration for it.  The cases where we
violated this rule fall into three roughly equal groups:
  * Stuff that should have been static.
  * Stuff that was global but where the extern was local to some
    other C file.
  * Stuff that was only global when built for the unit tests, that
    needed a conditional extern in the headers.

The first two were IMO genuine problems; the last is a wart of how
we build tests.

4f1a04ff9c Replace nearly all XXX0vv comments with smarter ones
So, back long ago, XXX012 meant, "before Tor 0.1.2 is released, we
had better revisit this comment and fix it!"

But we have a huge pile of such comments accumulated for a large
number of released versions!  Not cool.

So, here's what I tried to do:

  * 0.2.9 and 0.2.8 are retained, since those are not yet released.

  * XXX+ or XXX++ or XXX++++ or whatever means, "This one looks
    quite important!"

  * The others, after one-by-one examination, are downgraded to
    plain old XXX.  Which doesn't mean they aren't a problem -- just
    that they cannot possibly be a release-blocking problem.

ab932cd7bf Remove duplicate siging_key_cert fields.
With the fix for #17150, I added a duplicate certificate here.  Here
I remove the original location in 0.2.8.  (I wouldn't want to do
that in 027, due to the amount of authority-voting-related code
drift.)

Closes 19073.

00f74e0372 Improve API of routerinfo_incompatible_with_extrainfo()
This API change makes it so that routerinfo_incompatible...() no
longer takes a routerinfo_t, so that it's obvious that it should
only look at fields from the signed_descriptor_t.

This change should prevent a recurrence of #17150.

bf3e32a452 Fix out-of-bounds write during voting with duplicate ed25519 keys
In dirserv_compute_performance_thresholds, we allocate arrays based
on the length of 'routers', a list of routerinfo_t, but loop over
the nodelist. The 'routers' list may be shorter when relays were
filtered by routers_make_ed_keys_unique, leading to an out-of-bounds
write on directory authorities.

This bug was originally introduced in 26e89742, but it doesn't look
possible to trigger until routers_make_ed_keys_unique was introduced
in 13a31e72.

Fixes bug 19032; bugfix on tor 0.2.8.2-alpha.

0aacc07036 encourage rejected relays to contact us
When the directory authorities refuse a bad relay's descriptor,
encourage the relay operator to contact us. Many relay operators
won't notice this line in their logs, but it's a win if even a
few learn why we don't like what their relay was doing.

Resolves ticket 18760.

I didn't specify a contact mechanism (e.g. an email address), because
every time we've done that in the past, a few years later we noticed
that the code was pointing people to an obsolete contact address.

48f8229504 After we strip out duplicate entries from 'routers', don't use 'rl'.
We've got to make sure that every single subsequent calculation in
dirserv_generate_networkstatus_vote_obj() are based on the list of
routerinfo_t *after* we've removed possible duplicates, not before.
Fortunately, none of the functions that were taking a routerlist_t
as an argument were actually using any fields other than this list
of routers.

13a31e72db Never vote for an ed key twice.
When generating a vote, and we have two routerinfos with the same ed
key, omit the one published earlier.

This was supposed to have been solved by key pinning, but when I
made key pinning optional, I didn't realize that this would jump up
and bite us.  It is part of bug 18318, and the root cause of 17668.

1ceb7142a1 A relay now advertises "tunnelled-dir-server" in its descriptor
When a relay does not have an open directory port but it has an
orport configured and is accepting client connections then it can
now service tunnelled directory requests, too. This was already true
of relays with an dirport configured.

We also conditionally stop advertising this functionality if the
relay is nearing its bandwidth usage limit - same as how dirport
advertisement is determined.
